Abstract

The invention relates to the technical field of tunnel engineering construction, in particular to a tunnel collapse treatment method. The tunnel collapse treatment method comprises the steps that back pressing backfilling is conducted on a collapse body, back pressing is conducted on a collapse section and a traction section, and the collapse body is preliminarily stabilized; a primary support section is reinforced; a collapse cavity is backfilled, a collapse section arch frame, spraying concrete, backfilling bubble mixed light soil in the collapse cavity of the collapse section are replaced, and the arch frame and spraying concrete in a traction section are replaced. When the tunnel collapse treatment method is adopted for primary support lateral collapse treatment, on one hand, construction safety can be guaranteed, the engineering cost is reduced, the treatment time can be greatly saved, and good economic benefits and social benefits are obtained.

Description

Technical field[0001]The present application relates to the field of construction technology of tunnel engineering, in particular, to a tunnel collapse treatment method.Background technique[0002]The tunnel passes through the fault crushed or affects or causes stress release, and the surrounding rock caused by the surrounding rock caused by the surrounding rock, the surrounding rock caused by the stress. Thousands of rock rocks are very soft, broken, and poor stability. Some loose bodies are on top of the tunnel, and some are located in the wall of the wall. Some interleaved divisions, the location is difficult to judge, the construction is difficult, must be based on the geology Situation, surrounding rock stability, etc., Etc., Etc., Etc.[0003]The landslide has seriously threatened the safety, collapse of tunnels, collapse, and collapse work has become the primary issue of tunnel construction. The collapse section processing takes a basic criterion premised on safety, using the mos...
